[FONT='Times New Roman','serif']Some facts to dwell upon.[/FONT]
[FONT='Times New Roman','serif']According to Li et al (2007), “Random testing serves primarily as a preventive measure through its deterrent effect, which is presumably a function of the testing rate”.
A recent study in the US has shown that between 1997-2002, random testing highlighted 440 violations for alcohol, representing a prevalence rate of 0.09% among safety sensitive employees. The study concluded that alcohol was a valid risk for aviation accidents but, “in reality alcohol misuse as a contributing factor has been virtually eradicated from U.S. major airline accidents”. However the study did note the FAA’s alcohol misuse prevention program is likely to have played a key role in maintaining these low levels of violations (Li et al: 2007)
